Insulators vs. Conductors

Our journal sheet for this activity

Using a door hinge as a conductor

Today we explored insulators and conductors. The kids were given a baggy of 7 items - a binder clip, a dime, a penny, a Popsicle stick, an eraser, a pen, and a brad. They were also given the circuit supplies of a battery, wire, and a wire with a light bulb attached.

They were to test the items to determine if they were insulators or conductors. They did this by adding them to their circuits and observing whether or not they light came on. When they finished, they were to go around the room and find other things to test. Here are some pictures of the items they tested.

Electrical Circuits

In science we've begun to explore electrical circuits, and what they must have in order to be complete. The kids were handed a battery, wire, and another wire with a light bulb attached, then they were told to make the bulb turn on. That's the most direction they were given.

All groups were eventually successful in turning on the light. It's always fun to hear their conversations as they make their cases for why their way will be successful. Most groups figured out they didn't even need the extra wire!

 After they finished, we discussed what parts an electrical circuit needs to be complete. It must have a power source, conductor, something that needs the power, then finally the circuit must be closed. We also discussed the idea that while circuits don't have to have an insulator on the wires, it's probably a great idea. ;)
